DANGER
Improper installation and commissioning of the device
carries a risk of explosion.
For use in potentially explosive atmospheres, observe the
information in chapter „Use in potentially explosive
atmospheres according to ATEX and IECEx" on page 5 and
„Use in potentially explosive atmospheres in accordance with
FM and cCSAus" on page 16!
The electrical connection may only be established by
authorized specialist personnel and in accordance with the
connection diagrams.
The electrical connection information in the manual must be
observed; otherwise, the type of electrical protection may be
adversely affected.
Ground the measurement system according to requirements.
